Thank you again, So the master-ip is the virtual IP? I was thinking that was
the IP address of the master database server. Thank you for this. I am going to
try this and see if I can get it to function.
Thanks,
Keith

Hi Keith
Do you want to start "ClusterIP" on Slave ?
It seems that ClusterIP is based on vip-slave of my sample configuration.
If you would like to start it on Master, you need to customize "vip-master".
And pgsql's master-ip parameter needs the IP of vip-master which
combines with vip-rep.
